Can run after cancellation of the notes, annotations can't read running after failure, the reason is a string of problems, but if we don't change this kind of operation, what's the solution?
CodePudding user response:
Ifstream ofstream are to the operation of the file, so you write: ofstream OS (" gao ", ios_base: : binary); Ifstream is (" gao ", ios_base: : binary); If there are any questions around? In addition: is. Read (reinterpret_cast & lt; Char * & gt; (& amp; B), 16); Instead, turn a statement into public, is. Read (reinterpret_cast & lt; Char * & gt; (& amp; (b.a)), 16); Have a try
